Dolphin are fast growing, prolific and have a short life span - an average of 5 years. Average fork lengths for males and females ranges from 34 to 55 inches. Males grow faster and usually live longer than females. The spawning season varies with latitiude. Dolphin collected in the Florida Current spawned from November through July, and those collected from the Gulf Stream near North Carolina were reproductively active during June and July. Small females may spawn 240 thousand pelagic eggs, and fish larger than 43 inches may spawn several million. Dolphin are attracted to Sargassum, a floating brown alga, which serves as a hiding place and source of food. Other sources of food associated with the Sargassum include small fish, crabs, and shrimp. Dolphin may also pursue fast -swimming fish, such as flying fish or mackerels. Often man made garbage is entangled in the floating Sargassum, and is consumed by dolphin, which do not recognize the waste as a non-food item. Plastic wrappers, small light bulbs, rope and string have been removed form the stomachs of dolphin.
